My front brake lines are cracked (outer lining). I purchased two OEM lines to replace. I noticed each end is fixed, so I'm not sure how to install. The only thing I can think of is to attach one end on to the hard brake line, and remove the caliper to install on the other end. Has anyone done this repair before? Is it necessary to remove the caliper?

Thanks.
